NAME
Regexp::Trie - builds trie-ized regexp
SYNOPSIS
use Regexp::Trie;
my $rt = Regexp::Trie->new;
for (qw/foobar fooxar foozap fooza/){
$rt->add($_);
}
print $rt->regexp, "\n" # (?-xism:foo(?:bar|xar|zap?))
DESCRIPTION
This module is a faster but simpler version of Regexp::Assemble or
Regexp::Optimizer. It builds a trie-ized regexp as above.
This module is faster than Regexp::Assemble but you can only add
literals. "a+b" is treated as "a\+b", not "more than one a's followed by
b".
I wrote this module because I needed something faster than
Regexp::Assemble and Regexp::Optimizer. If you need more minute control,
use those instead.
TIPS
See t/dict2rx.pl to find how to convert a big dictionary into a single
regexp that can be later loaded as:
my $rx = do 'dict.rx';
EXPORT
None.
